Hi Silversurf
"Jungin," literally translated, means "pure silver."
Generally, Japanese "pure silver" was at the same standard or higher than sterling silver (92.5%), but as far as I know the mark itself did not indicate any definite percentage of silver.
There are many ways to test a piece for silver content, as discussed elsewhere in this Forum. Of course, a mere test cannot provide so accurate and absolute an answer as melting down the piece in question. If you do so with the cocktail shaker, I hope you will share the results with us.
Cheers
